Summary
An explanation is given of the variation withA, Z, of 1): the ratio of the probabilities of mesonic to nonmesonic decay of hyperfragments and 2) : the mean life of the hyperfragments. The explanation involves an exclusion principle inhibition of the bound hyperon mesonic decay. Some evidence is presented in favor of a Λ0 hyperon spin and parity (relative to a nucleon) of 1/2− (or less probably, of 1/2+ or 3/2+).
Riassunto
Si dà una spiegazione della variazione conA, Z: 1) del rapporto delle probabilità dei decadimenti mesonico e non mesonico degli iperframmenti; 2) della vita media degli iperframmenti. La spiegazione richiede l’inibizione del principio d’esclusione riferito al decadimento mesonico dell’iperone legato. Si presentano deboli prove in favore di spin e parità di un iperone Λ0 (rispetto a un nucleone) 1/2− (o, meno probabilmente,.
